Took like 15 tries but I beat it with Hera (L) Sabine and Ezra at XI, Kanan at X and Zeb at VIII. Sabine abilities maxed all omegas. Hera and Ezra abilities at 7 or maxed (w/o omegas). Kanan abilities at 7 to 3 and Zeb abilities at 6 to 3. I made a point of not using omegas aside from Sabine who I maxed months ago. I did not use my god/arena mods, just some good to okay ones I had stocked up. I finished it with Hera, Sabine and Ezra still alive.
I killed both DTs first then Thrawn then the STs. Zeb's daze is very important in that fight.
The final battle was hard. Actually it was very hard. I used up all the level 3 ability mats to give kanan and zeb a much needed boost which got me over the edge but it was annoying as I had saved them for Thrawn, where I had plenty of omega and zeta mats to use on him. But at least it got me past the event.
